Getting ready to put a rear main seal and better pan on the T. The pan has been bead blasted and is clean. I know I have seen the insides of pans "painted" and wondered if that would be a good idea since hot rods see periods of seasonal low use time. Even engines that get used everyday can have rust form from condensation. If yes, what is normally used to coat the inside of a pan or is it better to just leave it bare. You sure wouldn't want loose paint floating around the pan and clogging stuff up.
